Abstract

A method for controlling digital controller of wiper motor on automobile includes initializing chip and carrying out coding as per level size, judging whether it is on closed gear or not by microcontroller according to coding table, judging whether it is on intermittent gear or not if it is not, sending action command to motor driving chip as per different gear program if it is not or otherwise driving relevant gear coil to be operated by driving motor, judging whether homing signal is on low level or not and stopping execution if it is or otherwise maintaining operation on original gear and stopping wiper when homing signal is jumped to low level.

Description

technical field [0001] The invention relates to a control method of an automobile wiper motor. Background technique [0002] The car wiper that cleans the windshield of the car is powered by a general-purpose wiper motor, and most of them control the stop, movement, intermittent time and duration of the wiper motor through a mechanical control composed of a combination switch, timer chip and relay. Speed, so as to realize the functions of wiper cleaning, high-speed wipe, low-speed wipe and intermittent wipe. The following problems exist in the current control method: low reliability, low accuracy, and prone to mechanical failures. Contents of the invention [0003] In order to solve the problems of low reliability, low accuracy, easy mechanical failure and the like existing in the existing control method, a control method of a digital controller of an automobile wiper motor is provided. [0004] The digital controller of the automobile wiper motor includes a combination ...
